CROSS-MODAL FEEDBACK OF TACTILE AND AUDITORY STIMULI FOR CYCLISTS IN NOISY ENVIRONMENTS

In recent years, with the increasing use of bicycles for environmental and health benefits, the importance of the feedback for cyclists is increasing. Currently, navigation serves as the primary feedback, but traditional auditory instructions and visual information can lead to decreased attention and discomfort. Moreover, as bicycles account for 23% of all traffic accidents in 2022, improving bicycle safety is a crucial challenge. In order to explore methods for enhancing safety and improving cyclist feedback through auditory and tactile signals, experiments were conducted. During the experiments, the accuracy of recognition and reaction times for both tactile and auditory signals were evaluated in situations with simulated road traffic sounds. Subsequently, the effectiveness of cross-modal feedback was assessed, optimal signal conditions were examined, and the relationship between variations in environmental noise and optimal auditory signals for cyclists was discussed.
